Model SHH is the new 91% efficient separated-combustion addition to the Reznor brand line of pre-engineered air handlers. The first ever separated combustion system in the commercial/industrial heating industry was introduced on a Reznor heater in the 1960s, and that proven technology is continued in this new high efficiency separated combustion product.

Reznor's SHH is available in four sizes (130/180/260/350 MBH). Each size is designed for a minimum of 91% thermal efficiency and is available for use with either natural gas or propane.
